Alveolar Ridge Preservation With Different Grafting Strategies

Bone Resorption Clinical Trial

Official title: Comparison of Half- and Full-Grafting Alveolar Ridge Preservation With Different Sealing Materials: A Three-arm Randomized Clinical Trial

Status Completed

Clinical Trial Summary

The aim of the present study was to compare the half-packed grafts that are covered with either a collagen or a nonresorbable membrane to the conventional alveolar ridge preservation procedures involving full-packed grafts and collagen membrane. The primary purpose was to evaluate the bone dimensional changes between the groups, and the secondary objective was to assess the potential contributing factors to clinical, radiographic and implant-related outcomes under different alveolar ridge preservation procedures.

Clinical Trial Description

Regarding different surgical approaches in alveolar ridge preservation, limited studies directly compare collagen and non-resorbable membrane, and the comparison between half- and full- grafting strategy in clinical and radiographic outcomes was still lacking. The comparable effect of dimensional preservation between groups was shown except for more radiographic bone gain in full-grafting group. Contributing factors, including thin bone thickness , vertical root fracture related sockets, non-molar sites and large BPD might attenuate the effect of ARP. At implant placement, similar results in bone quality and keratinized mucosal width was found in all groups, while thicker vertical mucosal thickness was obtained when using nonresorbable membrane. All surgical modalities in alveolar ridge preservation yield stable peri-implant health 1 year after implant placement. ;
